To (ZZZ whom it may concern.-

Be it known that I, THEOPHILE LARAMIE, residing at South Chicago, in'the county of Cook and State of Illinois, and a citizen of the UnitedStates, have invented new and useful Improvements in Nail Plate FeedingMachines, of which the following is a full description, reference beinghad to the accompanying drawings, in which Figure 1 is a perspectiveshowing my feeding devices and a portion of a nail-machine. Fig. 1 is adetail. Fig. 2 is an elevation of the jaws which grasp the feed-rod.Fig. 3 is an elevation of the rack used to revolve the barrel whichturns the nail-plate, having an improvement of my own connectedtherewith.

Fig. 4 is a top view-of the jaws, the same being open- Fig. 5 is avertical section through the jaws. Fig. 6 1s a detail, and Fig. 7 is amodification.

The object of my invention is to provide improved devices for feedingnail-plates to machines used in making out nails.

My improvements consist, first, in providing a pair of jaws to grasp thefeed-rod, only one of which jaws opens, the jaws being whollydisconnected at both ends, and combined with other parts, as hereinafterparticularly described; second, in new devices for opening and closingthe jaws, consisting of a feed-bar working between the lower ends of thetwo jaws and closing the same, the jaws being opened by the action of aspring; third, in providing the feed-bar with a lever or arm by whichthe feed-bar is operated; and, fourth, in providing the feed-rack withset-screws, and in the other combinations hereinafter claimed.

My improvements are adapted to be used with various nail-feedingmachines now in use and operating upon a similar plan.

In the drawings, the right-hand portion, A, of Fig. 1 represents a partof a nail-machine, all of which is old except as hereinafter specifled,to which is attached my devices for feeding the plates to the machine.

13 represents the rack which is in use for revolving the barrel whichturns the nail-plate,

which rack is connected with. aswinging arm, 0, the lower end of whicharm 0 is pivoted in the usual manner. The only new feature about thisrack is the two set-screws a b, the

set-screw a being supported in a lug, c, and I) being supported eitherin the arm C or in an attachment, D, connected therewith.

E is one jaw which does not open, and F is a movable jaw.

G is a rod or shaft, one end of which is rigidly secured in the jaw E.The other end passes through an opening, d, in the jaw F, which openingis larger than the shaft G.

H are screws which pass through a yoke upon the outer end of a bar, I,which bar is rigidly connected with the machine A in the usual manner.This bar and yoke support the jaws. The ends of the screws H come incontact with'the ends of the rod or shaft G, forming pivotal points uponwhich the jaws have a limited rocking movement. The upper end of eachjaw is recessed. The jaw E is provided with a metal block, 0, held inplace by a screw, J, passed through slotst in the block and screwed intothe jaw E, the head of the screw bearing down on the block. The jaw F isprovided with a metal block, 0, held by a screw, J, passed through slottin the block and screwed into jaw F. The face of this block a isprovidedwith a piece of wood, f.

, g are screws to adjust the blocks 0 c, which are provided with slots tfor that purpose.

It is a screw which passes through the jaw E, the inner end of whichcomes in contact with an adjustable gage-plate, 2', upon the bar I, forthe purpose of limiting the rocking movement of the two jaws.

j are two pieces which are secured to the jaw E. i

k is a short rod which passes through the jaw F,with the ends of whichrod'k the screws I come in contact, the jaw F turning as it opens andcloses on this rod or pin 76.

m is a pin passing through a hole near the lower end of the jaw F, theother end of which is secured in the lower end of the jaw E.

n is a spring arranged to act upon the lower end of the jaw F, so as tomove it toward the jaw E, thereby opening the jaw F at its upper end.

0 are two pieces of steelone for each of the jaws E Fthe inner faces ofsuch pieces 0 being concave, as shown. j

K is a feed-bar, one end of which is ovalshaped, as shown in Fig. 5,such oval portion being located between the two steel plates 0. Theother end of this feed-rod K passes through and is supported in theswinging arm L otl the feeding-machine, which is pivoted near its lowerend, as usual.

p is astop with which the inner end of the bar-'K can come in contact.

1 is a spring, one end of which is secured tothe lower end of one of thejaws, and the other end is attached to an adjustable sleeve, 1', uponthe bar K, which is held in any desired position by a set-screw.

s is an adjusting -screw, the inner end of which comes in contact withthe outer end of the feedbar K.

M is an arm or lever near the inner end of the feed-bar K, preferablyadjustable thereon, and held in place by aset-screw. This arm M isarranged so that the screws a I) come in contact with the opposite sidesthereof as the rack 13 moves back and forth.

N is a feed-rod, one end of which is provided with jaws to grasp anail-plate, P, in the usual manner.

The lug 0 may be cast with the rack, as shown in Fig. 6, or may be madedetached therefrom and be secured thereto, as shown in Fig. 7. I

The operation is as. follows: The jaws are moved back and forth a littleby the rocking movement of the arm L, as usual. The devices which givesuch movement are not shown. A rocking movement is also given to thejaws for the purpose of carrying the nail-plate forward the properdistance, in the usual man ner. As the rack B moves back and forth, asusual, the point of the screw c and the head of the screw 1) come incontact alternately with the opposite sides of the arm or lever M, whichis secured to the feed-bar K, moving such arm M alternately in oppositedirections, and thereby giving a rocking movement to the feedbar K,which movement closes the jaw 13 every time that a partial rotation isgiven to the feed-bar K in either direction, which closing is caused bythe action of the oval portion 0 of the feed-bar K, which is locatedbetween the two jaws and near the lower ends thereof, as shown anddescribed. \Vhen this jaw is closed, the feed-rod N will be grasped, andthen the upper ends of the jaws will be carried forward, in the usualmanner, toward the main machine, which will advance the feed-rod N andthe nailplate l? the proper distance. The parts are so adjusted thatwhen the arm M stands vertical the oval part 12 of the feed-bar K willalso be verticahand then the action of the springn will bring thelowerends of the jaws together, opening the jaws at the top and releasing therod N, so that the upper ends of the jaws can move back preparatory toagain grasping the rod N. The upper ends of the jaws are thrown back bythe action of the spring q, and as the sleeve 1' is adjustable upon therod K the tension of this spring can be adjusted at pleasure by movingthe sleeve 1". By making the two jaws E F without any positiveconnection at either end, and by securing the jaw E upon the shaft G andproviding an opening through the jaw F for the shaft G larger than suchshaft itself, and by pivoting this jawF upon the rod orpin 7t andproviding the oval 1) upon the feed-bar, I am able to provide for therocking move ment of the two jaws together, and for the opening andclosing of the jaw F at the top every time that a rocking movement isgiven to the feed-bar K in either direction, thereby greatly increasingthe rapidity with which the nail-plate can be fed to the machine. vVhenby the movement of the arm L on its pivot the point of the feed-bar Kstrikes the stop 12, the other end of K will come in contact with thescrew 8 and the upper ends of the jaws will move forward.

What I claim as new, and desire to secure by Letters Patent, is asfollows 1. In a nailplate feeder, two jaws disconnected from each otherat both ends, each pro-' vided with a suitable recess near its lowerend,

in combination with a feed-bar having an oval' end, 1;, which enters thesaid recesses in the,

jaws, substantially as and for the purpose specified.

2. In a nail-plate feeder, two jaws, E F, in combination with a feedbar,K, provided with an arm or lever, M, through which a rocking movementcan be given to the feed-bar for the purpose of closing the jaws,substantially as specified.

3. A rack, B, provided with a 1), adapted to engage with the arm M onthe feed-bar K, for the purpose of rocking the feed-bar, substantiallyas and for the purpose screws or pins specified.

4. In a nail-plate feeder, two jaws, E F, supported as described, incombination with a rocking feedbar, K, spring q, and adjust able sleeve1', all constructed and operating substantially as and for the purposesspecified.

5. The jawsE F, recessed at the top, in combination with the blocks 0and 0, one or both of which are provided with a slot, and the screws 9,for the purpose of adjusting the blocks, substantially as specified.
